我想在iphone中使用同样的东西。 如果你想要使用100的注释然后下面是教程，这将有助于你。

在本教程中，如果您检查以下方法，它将解决您的问题。

  （void）plotCrimePositions：（NSData *）responseData {
 
（_mapView.annotations中的id< MKAnnotation>注解）{
 [_mapView removeAnnotation：annotation]; 
} 
 
 NSDictionary * root = [NSJSONSerialization JSONObjectWithData：responseData options：0 error：nil]; 
 
 NSArray * data = [root objectForKey：@data]; 
 
（NSArray * row in data）{
 
 NSNumber * latitude = [[row objectAtIndex：22] objectAtIndex：1]; 
 
 NSNumber * longitude = [[row objectAtIndex：22] objectAtIndex：2]; 
 
 NSString * crimeDescription = [row objectAtIndex：18]; 
 
 NSString * address = [row objectAtIndex：14]; 
 
 CLLocationCoordinate2D坐标; 
 
 coordinate.latitude = latitude.doubleValue; 
 
 coordinate.longitude = longitude.doubleValue; 
 
 MyLocation * annotation = [[MyLocation alloc] initWithName：crimeDescription address：address coordinate：coordinate]; 
 [_mapView addAnnotation：annotation]; 
} 
} 
  

I want to show 100 map points using MKMapView on same lat longs. Please see the link.

Same thing i want in iphone.

In this tutorial if you check the below method it will resolve your issue.

(void)plotCrimePositions:(NSData *)responseData {

for (id<MKAnnotation> annotation in _mapView.annotations) {
    [_mapView removeAnnotation:annotation];
}

NSDictionary *root = [NSJSONSerialization JSONObjectWithData:responseData options:0 error:nil];

NSArray *data = [root objectForKey:@"data"];

for (NSArray *row in data) {

    NSNumber * latitude = [[row objectAtIndex:22]objectAtIndex:1];

    NSNumber * longitude = [[row objectAtIndex:22]objectAtIndex:2];

    NSString * crimeDescription = [row objectAtIndex:18];

    NSString * address = [row objectAtIndex:14];

    CLLocationCoordinate2D coordinate;

    coordinate.latitude = latitude.doubleValue;

    coordinate.longitude = longitude.doubleValue;

    MyLocation *annotation = [[MyLocation alloc] initWithName:crimeDescription address:address coordinate:coordinate] ;
    [_mapView addAnnotation:annotation];
}
}
